By Sydney J. Freedberg Jr. on April 12, 2021 at 5:35 PM Obama Defense Secretary Chuck Hagel (left) swears in Christine Wormuth for her previous high-profile Pentagon job in 2014. UPDATED with Hill, AUSA endorsements WASHINGTON: The Biden Administration has tapped a veteran bureaucratic infighter to be the first female Secretary of the Army. Christine Wormuth not only headed Biden’s own defense transition team, taking over from DepSecDef nominee Kathleen Hicks. She’s been in and out of the Pentagon since 1996, with stints at the National Security Council and as director of International Security & Defense Policy at RAND, the influential thinktank. That gives her extensive first-hand experience in how the policy sausage gets made – and deep personal knowledge of the players at the Biden Pentagon.
